Hey there, fellow farmers! As a supplier of 120hp tractors with 4WD and 4 - row planting tools, I've seen firsthand how important it is to keep your equipment in top - notch condition. One of the most crucial maintenance tasks for your tractor is changing the oil filter. In this blog, I'll walk you through the process of changing the oil filter of a 120hp tractor with 4WD and a 4 - row planting tool.

Why Change the Oil Filter?

Before we dive into the how - to, let's talk about why changing the oil filter is so important. The oil filter plays a vital role in your tractor's engine. It traps dirt, debris, and other contaminants that can cause wear and tear on your engine parts. Over time, the filter gets clogged, and when that happens, it can't do its job effectively. A clogged filter can lead to reduced oil flow, increased engine temperature, and ultimately, engine damage. By changing the oil filter regularly, you can extend the life of your engine and keep it running smoothly.

Tools and Materials You'll Need

First things first, gather all the tools and materials you'll need for the job. Here's a list:

  • A new oil filter: Make sure it's the right one for your 120hp tractor. You can usually find this information in your tractor's owner's manual.
  • An oil filter wrench: This tool will help you remove the old filter.
  • A drain pan: To catch the old oil when you remove the filter.
  • A funnel: To pour the new oil into the engine.
  • New engine oil: Check your owner's manual for the correct type and amount of oil for your tractor.

Step - by - Step Guide to Changing the Oil Filter

Step 1: Prepare Your Tractor

Park your tractor on a level surface and turn off the engine. Let the engine cool down for at least 15 - 20 minutes. This is important because the oil and engine parts are hot when the engine is running, and you don't want to get burned. Also, make sure the parking brake is engaged.

Step 2: Locate the Oil Filter

The oil filter is usually located near the engine. Refer to your tractor's owner's manual if you're having trouble finding it. Once you've located the filter, place the drain pan underneath it. This will catch the oil that will come out when you remove the filter.

Step 3: Remove the Old Oil Filter

Use the oil filter wrench to loosen the old oil filter. Turn it counter - clockwise. Be careful because the filter may be full of hot oil, so it might spill a bit. Once the filter is loose enough, you can usually remove it by hand. Let the oil drain into the pan completely.

Step 4: Prepare the New Oil Filter

Take the new oil filter and apply a thin layer of fresh engine oil to the rubber gasket on the top of the filter. This will create a good seal and make it easier to install.

Step 5: Install the New Oil Filter

Carefully screw the new oil filter onto the engine by hand. Turn it clockwise until it's snug. Don't over - tighten it, as this can damage the filter or the engine. You can use the oil filter wrench to give it a final quarter - turn for a secure fit.

Step 6: Add New Engine Oil

Use the funnel to pour the new engine oil into the engine. Check your owner's manual for the correct amount of oil. You can usually find the oil fill cap on top of the engine. Slowly pour the oil in, and periodically check the oil level using the dipstick. Stop adding oil when it reaches the appropriate level on the dipstick.

Step 7: Check for Leaks

Start your tractor and let it run for a few minutes. Keep an eye on the oil filter area to make sure there are no leaks. If you see any oil dripping, turn off the engine immediately and check the filter again to make sure it's installed correctly.

  • Check the oil level daily before starting the tractor.
  • Inspect the air filter regularly and clean or replace it as needed.

  • Filter won't loosen: If the oil filter is really tight and won't come off with the wrench, you can try using a strap - style filter wrench for more grip. You can also tap the end of the wrench gently with a hammer to loosen it.
  • Oil is leaking after installation: If you notice oil leaking from the filter after you've installed the new one, it could be because the filter isn't tightened properly or the gasket is damaged. Remove the filter, check the gasket, and reinstall it, making sure it's tightened correctly.
